Having had seen the creatures close by quite a bit in my life. ...I was curious about their meaning.
Mallards are symbolic of emotions, as they are associated with the water element. They help in reminding one to take care of their emotional self, to nurture, and be easy on the spirit. They represent being able to handle your emotions with grace and strength. And after spending time with this mallard, I find they teach one to trust their instincts about others..and align yourself with those that have a kind spirit, fostering healthy relationships. (In Feng Shui, Mallards are symbolic for relationships and commitment)
